3 Claims.

{My invention relates to a ventilator construcion. I

One of the objects of my invention is to provide an improved ventilating system for automobiles by means of which the warm, stale air may be drawn out of the interior of the car without creating unpleasant drafts.

- A further object of my invention is to provide such a construction in which the degree of suction caused by the ventilator may be controlled by raising or lowering the window adjacent the ventilator.

A;further object of my invention is to provide such a construction in which airv drawn in through the cowl ventilator passes down around the feet of the occupants of the car and is thence drawn out through the opening above the sliding window glass. A-further object of my invention is to provide a construction of the type indicated above in whieh. when desired, an adjustment may be made whereby the air, instead of being sucked outofthe car, will be caught and forced into the car in order to cause a rapid circulation of air within the ear.

" Further objects and advantages of the invention will be apparent from the description and claims.

vIn the drawings, in which two forms of my invention are illustrated,

Figure 1 is aperspective view of the front end of, a car showing my improved ventilator;

Fig.2 is. a perspective View of the suction ventilator attachment; I

Fig- 3 is a section on the line 33 of Fig. 4; Fig. 4 is a-plan view of the ventilator attachment;

Fig.5 is a side elevational view showing a modified form in which the glass in the ventilator 40 is adjustable to scoop air in when desired; Fig. 6 is a section on line 6-6 of Fig. 5;

Fig. '7 is a. section on the line l-'l of Fig. 6; and Fig. 8 is a section on the line 8-8 of Fig. 5.

Referring tothe drawings in detail, and first to Figs. 1 to 4, inclusive, the construction shown therein comprises the front part of a car having an adjustable cowl ventilator I, a door 2 having a, window frame in its upper portion in which a glass. pane. 4 is vertically slidable, and a suction ventilator attachment 5 for drawing air out of the 'car above the upper edge ofv the adjustable sliding pane 4. A ventilator may be provided on both front doors, or on all of the doors, if desired, or on any panel having a window frame in which a glass pane is adjustable to control the amount of suction.

In the construction shown, with the cowl ventilator open, there will be a circulation of air, as indicated by arrows A, in through the cowl ventilator I, down around the'feet of the occupants of the car, and thence upwardly and outwardly through the opening above the sliding glass pane 4, this circulation being effected by the suction action of the ventilator attachment 5 caused by the travel of the car.

If the cowl ventilator is closed, the suction created by the ventilator attachment still causes the warm, stale air to be drawn out of the interior of the car, fresh air being supplied at innumerable points in the body construction, such as the openings around the doors and windows, etc. With the cowl ventilator closed and the ventilator constructions provided on the front doors, the air within the car gradually moves forward as a mass and is drawn out above the upper edges of the sliding glass panes. In this construction, it will be noted that there are no moving parts to get out of order, no adjustments to be made, and no strain on the venti lator glasses to result in breakage. It will also be noted that there are no dangerous chilling drafts occasioned by this system of ventilation, but rather a gradual movement of the air within the car toward the low pressure area created by the ventilator attachments.

Each of these ventilator attachments comprises a unitary glass supporting frame which is rigidly secured to the window frame in any suitable manner, as by means of screws which may either be screwed in from the outside of the frame or may be inserted from the inside of the door and screwed into the frame. This unitary frame comprises an upper portion 6 extending along the upper portion of the window frame for supporting the glass and sealing between the upper edge of the glass and window frame, a front portion 1 extending along the front portion of the window frame and sealing between the front edge of the glass and window frame, and a lower portion 8 extending along the low-- er portion of the window frame and sealing be tween the lower edge of the glass and window frame. It will be noted that the upper and lowor portions of this unitary frame prevent dust, draft, rain, snow, flying particles, and insects from entering the car. It will also be noted that the circulation of air effected by this suction ventilator keeps the windshield and windows from clouding or frosting. It will also be understood that circulation is such that the occupants of the back seat are not exposed to disagreeable drafts and to smoke blowing back to the rear of the car.

With this construction, the car can be driven in a driving rain without closing the windows on either side, although if the wind is directly from the side and it is a strong wind, it may be necessary to close the window on one side. In ordinary rains, however, the windows on both sides can be left open because of the outwardly-deflected air currents created by the action of the ventilators.

The construction shown in Figs. 5, 6, 7, and 8 can be used just as the construction previously described. However, there are some car users who, on occasion, like to have a current of air directed against their faces and bodies and for such users the adjustable type of ventilator may have an appeal. For this purpose, the glass 9 in the ventilator attachment is made adjustable so that it may be swung from a sealing engagement with the frame to the full-line position shown in Fig. 6, in which, instead of causing air to be sucked out of the car, it will scoop air into the car. For this purpose, the glass pane 9 is mounted in a pair of hinge clips which are substantially in axial alignment. The lower hinge clip comprises a channel portion ID in which the lower edge of the glass is firmly seated and secured, and a hing-e arm II having a pivoted frictional connection with the lower frame portion, as shown in detail in Fig. '7. This hinge connection comprises a screw l2 extending through an opening in the hinge arm and frame portion and threaded into a nut l3 seated in a pocket in the lower side of the frame portion 8. Suitable friction washers l4 may be provided for the purpose of holding the glass in any position to which it may be adjusted.

The upper clip hinge comprises a clip portion l5 for embracing the upper edge of the glass and a hinge arm i5 having a pivotal connection with the upper frame portion. This pivotal connection, shown in detail in Fig. 8, comprises a pivot pin l1 having a tapered portion engaging a correspondingly-tapered opening in the frame portion 6 and a set screw l8 for holding the taper pin in the hinge arm. The taper pin may be adjusted to give the desired frictional engagement with the tapered opening to further assist in holding the pane in adjusted position.

By swinging the pane outwardly to the position shown in Fig. 6, the occupants of the car can cause air to be scooped in to direct strong currents of air into the interior of the car when desired.

In both the forms shown, the glass may be seated in suitable channels in any usual or suitable manner. the frame may be provided with a flange 19, against which the glass swings and closes snugly when in suction-creating position. A suitable packing strip, such as a small rubber tube 20, may be provided for the glass to bear against to make a weather-tight engagement and to prevent rattling.-

Further modifications will be apparent to those skilled in the art and it is desired, therefore, that my invention be limited only by the prior art and the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
